This invention relates to a metal car end.

and concerns itself with a corrugated structure having terminal flanges into which the corrugations extend, said terminal flanges being secured to the corner posts'of the c-ar, the

nated short of the sides of the car or the attaching margins of the panels, producing weakened sections adjacent the corners of the car. To overcome these weakenedsections, it has been proposed to stamp additional short corrugations at the ends of the panels, such additional corrugations extending inwardly a short distance betweenthe regular corrugations. Such a structure has not proved satisfactory since it interferes with the attaching margins, unduly stretches thematerial from which it is formed and fails to give the required rigidity and strength.

The above objections are obviated in this in- 25 vention due to the mergingofthe corruga'tions into the attaching flanges whereby a strong and rigid corner structure is provided that will withstand the most severe interior impact. The invention comprises the novelstructure so and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

As shown on the drawings:

In order that this invention may be readily understood, there is shown in Figure 1 an end of a car which is constructed according to this invention. It will be noted that this endcomprises a pair of corner posts 1, each of which embodies a 2 bar 2 having an outwardly extending flange 3 with an overhanging lip 4. The corrugated metal panel=is confined between the flanges 3. As shown the metal pane-l consists of alower section 5 and an upper section 6, which are riveted together as indicated at 7 This panel is provided with longitudinal corrugations 8 and terminal flanges 9 into which the corrugations merge or extend for bracingfand rigidifying the same. The flanges 9 are riveted or secured to the outstanding flanges 30f the Z bars with the ends of the flanges abutting the lips 4 in order to eliminate or reduce'the shear on the rivets or securing means when there is an outward thrust against the end of the car. In

Figures [to 4, the invention is shown as apflange 3 extending rearwardly.

In Figure 4, the rear end structure is similar to that already describedwith the exception that the 2 bar 2- has one flange engaging .the rear end of the post 1; the flanges of the panel being secured to the webs of theZ bars with the ends thereof engaging the overhangin g flange 3 to reduce or eliminate shear with respect to the rivets or attaching means.

In Figures 5 and 6. the invent-ion is shown as applied 'to a double sheathed wooden car having corner posts 10. In Figure 5, a 2 bar having an outwardly extending flange.

is secured'to the post 10, and flange 9 of the {provided a rigid .structure and the eng panel, engages the outersidec'ofthe.flanges I 7 posts 13 whichembody Z bar 2.- In this case,

the Z bar and to the inner side Walls bar.-

3, being secured thereto by rivets or other :means. It will be noted in Figure '5 that the ends of the anels are bent outwardly for this urpose. nFigure 6, the corrugated meta. panel is rovided upon its lateral ends with right-ang ed offset portions comprising the portion 11, which is attached to the flange a corrugated metal panel having terminal flanges into which the corrugations extend,

and means forsecuring portions of said flanges to ortions of said Z bars with other portions 0 said flanges engaging other por- 3, and a portion 12 which extends under the web of the Z bar and is secured thereto: This ment of the portion 12 under the web of the Z bar2, reduces add eliminates the shear on the rivets or attaching means. 7

In Figure 7 ,there is shown a fragmentary portion of a single sheathed car having corner the metal panel is provided with a relatively long inwardly extending flange 14, which is secured, to both the outstanding-flange f The rmatter of attaching the'panel to the to of'the car isshown in Figure 8, and re erring to said figure, it'will be noted that the to of the: panel is secured to the transverse eam 15 which extends across the car at substantially the upper end of the corner post. The manner of attaching the panel to the bottom of the car is. shown in Figure '9, and in referrin to said figure, it will be noted that an ang e member 16 is secured to some ap ro riate part of the bottom of the car, pre era ly the floor, and the 1ower edge of the panel is secured to the angle 16.

It will be appreciated that in havin the corrugations extend the full width 0 the panels, and merging or extending them into the attaching flanges of the panel, a rigid and durable structure .is obtained. which eliminatesthe weak .section that heretofore existed where the corrugations terminated,

some distance from the ends of vthe panel. It will'alsohe appreciated that inhaving the attaching flanges secured to one'flange,

of the Z 'bars'and engaging another flange at right ,angles to. sue attaching flange, the

shear on the rivets or attaching means is "greatly reduced or eliminated.

We are aware that many changes may be made, andnumerous details of construction may be varied through a wide range without departin from the principles of this invention, an 'wetherefore do not purpose'limiting the patent I granted hereon, otherwise than necessitated by the prior art.

We claim as our inventionn i 1.. In a corrugated car end, apair of corner posts, each embodying a .2 bar, a corrugated panel having flanges attached to said Z bars,

said flanges andZ bars having abutting parts tending to reduce the shear at the attached parts.

2; In a corrugated car end, a pair of opposed corner posts, each embodying a Z bar,

of the tions of the 2 bars for the purpose set forth;

3, In a corrugated car end, a pair of corner posts each embodying aZ 'bar, a corrugated m'etai Z bar.

4. In a corrugated car end, a pair of corner posts, each embodying a Z bar, a corrugated metal panel having terminal right angled ofisets secured beneath'the webs and against the outstanding flanges of the Z bars. 7 5. In a corrugated car'end,a pair of opposed corner posts,,each embodying an angular member, and a corrugated sheet metal panel having terminal right angled attaching portions into which the corrugations merge, said.

attaching portions being secured to one flange of said angular members and engaging a p or post's, having rearwardly directed flanges,

and a'corrugated metal panel having parts attached to said flanges, and parts in abutting relation with said flangs for resisting rearward thrust, the corrugationsof said panel extending between the first mentioned parts and merginginto the same.
